So on friday afternoon I got a lovely phone call from Audi MK reminding me that my cambelt is due a change as my S3 is coming up to 5 years old. It's on 21k miles! I wasn't aware of this as Audi managed to lose the service schedule so i've got a replacement which gives you no information on service schedules for the vehicle. Can anyone tell me how often the Haldex needs oil & filter on the S3 8P2? Best start saving now!
